Application filed May 81, 1923;

The invention is an improvei'nent in spinning devices of the live-capclass and has for its general object to provide in improved manner forthe mounting and driving of a cap, as well for the retardation of thecap in its rotation which, through producing a difference in the ratesof rota-- tion of the spinning element and the cooperating cap operatesas a factor in occasioning the winding of the spun yarn upon thespinning element.

An illustrative embodiment of the invention is shown in Fig. l of thedrawings, which represents, partly in section, an organizationcomprising the essentials of the invention. Fig. 2 shows theclutch-device in horizontal section.

Organized spinning devices of the live cap class comprise a cap 1mounted upon the blade or barrel of arevolving-spinning element 2 andrevolving in unison with such element, and one or more bearing elementson the order of those shown at 4, 5, coacting with the cap. Therevolving spinning element 2 in the drawings is a bobbin, only partlyshown, which is mounted upon a spinning spindle 3, only partly shown.The cap is mounted upon the blade or barrel of the spinning element bymeans of a central hole 11 in the head of the cap, such hole being soproportioned that the wall of the said hole, at the smallest diameter ofthe hole, has a close but easy sliding fit upon.

the said blade or barrel. The easy sliding fit permits the cap togravitate downward upon the said blade or barrel until it is supportedby the bearing element or elements (4:, 5). It also permits the traversemovements of the cap up and down upon the blade of barrel which arerequired to take place for the distribution of the spun yarn upon theblade or barrel in being wound thereon. The bearing element or elementshas or have been a wheel or wheels. as in the case of the bearingelements shown at 4, 5, and has or have been arranged in differentrelations for controlling the cap vertically, or laterally, or bothvertically and laterally, in different instances. The wheel or wheels,commonly termed pivots or pivot wheels, has or have beenrevolublymounted 011 a supportor supports carried by a rail 6 to whichin practice vertical traversing movements are given. A convenient formof support for the pivot wheels Serial No. 642,379.

4, 5, is represented at 51 in Fig. l. In the operation of the spinningdevices, the yarn being spun'passes down alongside the cap and aroundthe edge Or lip at the bottom of 'the cap to the spinning element 2,upon which it lS- wound; As the rail 6 goes up the ap is raised by thebearing element, or

elements upward along the blade or barrel. As the rail goes of thespinning elen'icnt. 4 down the cap gravitates downward upon said bladeor barrel. following the bearing element or elements downward.

In the case of early instances of live-capwhich the cap made contactvertically. In

the case oflater instances. the splined or'key and groove clutch forcausing the cap to be positively rotated beingretained, the hearingwheels, in addition to being adaptedto support the cap vertically, wereformed and arranged to operate, through contact with peripheral portionsof the cap, to prevent the cap from becoming locked to the blade orbarrel of the spinning element in a manner which would interfere withfree vertical movement of the cap up and down upon the said blade orbarrel in conformity with the upand down movements ofthe traverse. In

all these instances it was found thatvibration of the spindle,v andother causes, inter-' fered with reliability of action of the cap; andby reason of the cap being revolved at the same rate of speed as thespinning element the cap had no effect in producing retardation of thecircling movement of the yarn in being spun, so as to promote thewinding of the yarn upon the spinning element, so that variousexpedients were employed to retard the yarn in its revolution with thespinning element, to cause it to wind upon the latter. In the case ofstill later instances thesplined or key and groove connection has beenomitted, and for the purpose of insuring rotation of the cap the bearingelement or elements cooperating with the latter has or have beenarranged, etc, to cant or tilt the cap slightly relative to oi thespinning clean-at.

the blade or barrel of the spinning element so as to cause the bearingin the cap head to crarop or bind. a little upon said. blade or ban rel.ln the case ol a l riclionallv driven cap this cran'lping or binding isuseful l'or can ing the cap to start promptly into rotation in startingup the spinning; 'l'rame after a stoppage oil the frame, or in startingup the individual spinning element alter piecing up a broken end ofrare. The oantingr or tilting: has been occasioned through elugigementof the peripl'iery of an external lateral beat-inn nicn'iber constitutedb" a bearing wheel or pivot with the outer side or periphery of the carnear the lower edge oil the cap. Thereby the cap has been given a slighttilt away from the lateral bearing; member, such tilt operating to bringthe lower portion of the central bearing: of the cap head into closecontact with that side of the spinning element which is adjacent saidlateral bearing n'ielnben and also operating; to cause the spinningelement to be 'lrictionally gripped between upper and lower portions ofsaid central. bearing. However, (ranting or tipping of a cap, and resultant cramping or binding of the same upon a spinniiug clement. have thedrawback that they clutch or look the cap to the spinnino; element insuch manner as to prevent the free relative axial movement that isnecessary for the distribution of the yarn up and down upon the spinningelement, i. e. as the traverse occurs. Such canting or tipping alsoresults in the cap being caused to rotate upon an axis that is slightlyinclined with respect to that on which the spinning element rotates sothat the cap rotates out (it true coneentrioitv with the blade or barrellore or less llrcpgularitv of action, vibration and chattering; and moreor less accidental. up and down movement ol, the cap relative to thespinningelei'nent are observed. all of: which it is ill!- portant andadvisable to eliminate.

The said balls in the (hltWlIlgS are gentlypressed inward into contact with the blade or barrel. of the spinningelement by means of encircling band springs S,

The mode of operation is as follows:

The spinning element being at rest the cap is sustained vertically byits edge or lip resting upon the beveled peripheral surface ofpivot-wheel L, and by the contact of the liari-ng periphery of the capwith the pi=votwheel 3. By the support afforded by the two pivot-wheelsacting conjointly, the cap is sustained in an upright intermediatepcsition, without cramping or binding upon the blade or barrel of thespinning element. As the spinning element begins to rotate thefrictional contact between the blade or barre l thereof and the interiorsurface of the bore or hole in the cap-head, or the light clutchingaction of the ball-clutch, causes the cap to turn with the spinningelement. Contact of the cap with the respective pivotwhcels operates toretard the rotation of the cap, for the purpose of causing the yarn towind upon the spinning element as fast as spun, and in accordance withthe rate of delivery of the roving from the usualfront rolls. Thecontact of the flaring periphery of the cap with the periphery of theradiallydisposed pivot-wheel 5 acts with a tendency to lift the capslightly so as to relieve the bevel pivot-wheel d from carrying theweight of the cap, which reduces the wear which would necessarily comefrom the edge or lip of the cap resting entirely upon the beveledsurface of pivot-wheel 4.

The tendency of the cap in relation to the beveled pivot-wheel a is torun or ride on the lower portion of the bevel. This tendency acts tocrowd the cap lightly into contact with the periphery of theradially-disposed pivot-wheel 5. The contact of the flaring periphery ofthe cap with the radially-disposed pivot-wheel 5 acts to crowd the capreversely toward the bevel pivot-wheel a. Any pressure of the cap actingagainst pivot-wheel 5 will tend to force the edge or lip of the capagainst the beveled surface of pivot-wheel 1. thus causing it to ride ona higher part of the bevel. The conjoint action is to resist slightlythe rotation of the cap, thus checking or retarding the rotation of thecap in an improved manner.

The increased. flare of the inside bearing; of the cap-head allows moreside-play of the lower portion of the cap, and without any positiveclutching of the cap to the blade or barrel of the spinning element butwith resulting increased interference between the cap and the twoopposing pivot-wheels. That is to say, the flaring hole in the capheadpermits a suilicient amplitude of swinging or tilting of the cap withoutincreased binding or cran'ipil'ig of the cap to the spinning element.The said interfer cnce is on the order of a braking action in which thetwo pivots exert a tendency to retard the rotation oi the cap. Suchbrallug action is applied extvrnally.

Que bevei pivot l is employed to each cap.

The driving action between the blade or barrel of the spinning elementand the cap is such as to be effective, after the stopping of thespinning element, to cause the cap to start up in unison with suchelement in restarting the latter. The braking or interfering action ofthe two pivot-wheels 4: and 5 operates thereafter to effect theretardation of the cap which ensures the winding of the yarn, as spun,upon the spinning ele- HWY-t2. l

The ball-clutch devices shown in the drawings coinprisetwo circularseries of balls, one above the other, in an annular ball-container 9. asin my application filed Dec. 26, 1922, Serial No. 608.809, the saidballs tending radially outward under the influence of centrifugal force,utter the cap has assumed suii'icient speed of rotation, so that duringthe regular running of the spinning frame in which the devices areemployed the cap is driven chiefly by light frictional action. Thecircular arrangement of the two series of balls causes the clutchdevices to act uniformly around the spinning element and with a tendencyto centralize the cap into concentricity with the spinning element,without canting or cramping of the cap.
